Chevrolet Impala ignition issue with engine continuously cranking even after key removal on Chevrolet Impala

Some Chevrolet Impala owners report experiencing issues where the engine continues to crank even after the key has been removed. This problem may be linked to the security system, particularly if the Pass Key light remains illuminated after attempting to start the engine. Additionally, issues with the ignition switch or starter relay could lead to continuous power being supplied to the solenoid, keeping the starter engaged. Some owners have noted that a slow or weak engine crank may indicate underlying problems with the starter or battery. Furthermore, a worn key or malfunctioning ignition switch could inadvertently trigger the passlock system, resulting in persistent cranking. It is recommended for owners facing these issues to consult a qualified mechanic for proper diagnosis and resolution.
